An attempt to locate substorm onsets using Pi1 signatures
Read more of: An attempt to locate substorm onsets using Pi1 signaturesPi1 observations, because of their higher frequency, hold the promise of providing better temporal resolution for accurate timing of substorm onsets, thus continuing to be a matter of considerable importance […]

Diversity of mitochondrial DNA in three species of great whales before and after modern whaling
Read more of: Diversity of mitochondrial DNA in three species of great whales before and after modern whalingThe 20 th century commercial whaling industry severely reduced populations of great whales throughout the Southern Hemisphere. The effect of this exploitation on genetic diversity and population structure remains largely […]

Genetic diversity and demographic history of the leopard seal: A Southern Ocean top predator
Read more of: Genetic diversity and demographic history of the leopard seal: A Southern Ocean top predatorLeopard seals (Hydrurga leptonyx) are top predators that can exert substantial top-down control of their Antarctic prey species. However, population trends and genetic diversity of leopard seals remain understudied, limiting […]

Harnessing Diesel-Degrading Potential of an Antarctic Microalga from Greenwich Island and Its Physiological Adaptation
Read more of: Harnessing Diesel-Degrading Potential of an Antarctic Microalga from Greenwich Island and Its Physiological AdaptationPhytoremediation is a plant-based approach to extract, stabilise, eliminate, or render pollutants into less harmful form. The study highlights the use of a native polar microalga as a means of […]

The warming of the Southern Ocean and its significance
Read more of: The warming of the Southern Ocean and its significanceThe Southern Ocean encircles Antarctica and extends north to abut the subtropics at ~30-35°S. The Southern Ocean is a difficult place to collect measurements because it is far from many […]

Terrestrial non-native species in Antarctica: introduction, impact and management response
Read more of: Terrestrial non-native species in Antarctica: introduction, impact and management responseNon-native species introductions and establishment are having substantial and likely irreversible environmental impacts on Antarctic ecosystems and biodiversity. Non-native species, or species that live outside of their natural range, can […]

High‐resolution diving data collected from foraging area reveal that leatherback turtles dive faster to forage longer
Read more of: High‐resolution diving data collected from foraging area reveal that leatherback turtles dive faster to forage longerDespite multiple studies examining the diving behavior of leatherback sea turtles (Dermochelys coriacea) at coarse resolution over broad distances, there is still a paucity of high-resolution diving data collected in […]

Cryophilic Tardigrada have disjunct and bipolar distribution and establish long-term stable, low-density demes
Read more of: Cryophilic Tardigrada have disjunct and bipolar distribution and establish long-term stable, low-density demesGlaciers are inhabited by various cryophilic organisms ranging from single celled to multicellular, like Tardigrada (water bears). Owing to their scattered distribution, glaciers represent extremely fragmented habitats, and it remains […]
